JOHN or MICHAEL:
If you name your kid John or Mike, he can expect a lifetime of someone yelling, "Hey, Mike," and five guys turning around at once, going, "Which Mike are you talking to?" Don't give your kid a name that he's likely to have to share with a bunch of other people.
DANIEL or STANLEY:
If you give your son a name that rhymes with "man," he can expect that about ten times a day, some wiseass is going to walk by him and say "Dan the man!" with the exact same amount of self-amusement every time. It's going to get old really quickly, and if Dan or Stan are, in actuality, not particularly masculine, the guy saying the line will enjoy it even more, because of the irony.
CHASTITY:
If you give your daughter a stripper name, she can expect a lot of people asking if she's a stripper, and finding the question amusing every time. This will be even more awkward if she actually does become a stripper, because not only will she have to deal with people asking her if she's a stripper when she's not performing, but she'll also have to deal with people in the club who don't believe her when she says, "Yes, that actually IS my real name."
CHRISTIAN:
Unless he actually becomes a practicing Christian, this name is just going to confuse people. Imagine if he converts to Judaism, and has to introduce himself as "I'm Christian; I'm Jewish." It's like a religious Who's-On-First routine.
SHAWN:
I speak from experience on this one. Most people are familiar with the traditional Irish spelling of SEAN. If you give your kid an alternate spelling of a common name, he's going to spend the rest of his life having to correct people on it.
ALEXA:
Every time you call her name, your appliances will answer.
ADOLPH:
For obvious reasons.
I'll add more names to the list as I think of them.
